In the process of repainting my '71 and adding the bulkhead 6 engine mount. While the car is all apart I remember seeing someone do an access panel in the bulkhead for "emergency" engine access.
Does anyone have pictures of such a modification? TIA.

Recently been looking at this. Here is a thread with a few of them shown. One way is to use an extra firewall sheetmetal to make a nice form fitted panel. (IMG:style_emoticons/default/smile.gif)

With the right tools, you can easily change the fan belt, without cutting the firewall. I finally cut a hole when it was time to change the alternator. I did not want to drop the motor. I used PMS's fiberglass cover. https://patrickmotorsports.com/products/bod...K9wRboJZifp87C7

On my 2nd 6, back in the mid-80's, we did an access panel when we swapped in a 3,0. I got a section of firewall from a wrecked 914 and we used riv-nuts in the firewall with a nice weatherstrip around the hole and overlapped the new panel about 1" all the way around. Painted to match and it sealed really nice and I never could detect any louder engine noise as a result. (IMG:style_emoticons/default/beerchug.gif)

Is your current /6 (3.6 monster by the way) your 3rd, 4th, ...

Some guys are very fussy with cutting the firewall, I cut mine and sealed it up. If a fire burns long enough to get through, we will be having other problems for sure

Just remember, it's called a FIRE-Wall for a reason.

Don't use any flammable materials, not even for the sealing/gasket. It can make all the difference between having 30 seconds to get out of the car and burning alive.

Make it tight fitting like the post #3, you will be fine. It's easy to change the belt, check timing, not so good for removing the alternator

It is an issue but then Porsche designed in a pretty direct hole from the fuel tank and into the cabin. I have one. Made from a wrecked salvaged panel with a big overlap and lots of fasteners that are real bolts and nuts (welded).

I have lived an engine fire. I will do anything to prevent another one, and if it does happen, anything to slow it down.

NEVER CUT A HOLE IN SOMETHING CALLED A FIREWALL. It's the equivalent to cutting a hole in a parachute so you can see the sky better.

Well sure, you are cutting a hole but then you are covering it up. Most 914 & 911 fires seem to be caused by old fuel lines. I’m betting that the guys cutting access panels for their six’s have modernized their fuel delivery.

We have stainless steel lines in all these of our 914s. And I still will not cut a hole in a firewall. An intact firewall may make the difference between getting out of the car injury and some really awful burns.

I think that you make a good argument.
As a lifelong scientist, I am curious. One thing that I would like to know would be the level of firewall distortion that might be expected in a very bad but survivable impact. From any direction. One would want to see the worst damage and thus seal loss that might be expected. Another factor would be how often the back window might fail in such an accident, as fire in the engine compartment would travel through that space as well if it existed. I am driving a ‘72, with less protection than offered my ‘76. It is of some concern too.

Having the steel firewall is great, but having the rear glass at your head level with ordinary (tempered) glass is a problem. The rear glass will fail much sooner than a smallish access panel in the firewall.

I cut an access panel when I did my recent /6 conversion and made sure it is sealed.
